Tie up sizes 14-18, because the dortheas should be in pretty good numbers by then and the invaria and rontundas should still be at it.

Tail: Dun Hackle fibersBody: 30% Yellow, 30% Cream, 40% Orange superfine dubbing mix, you have to mix it yourself I dont know if the sell any mixtures like that.Hackle: Medium DunI rarely put wings on my sulphurs but if you want to put some medium dun hackle tips in for wings then that should should work well.

For the Comparadun I replace the medium dun hackle with deer hair wings.

Fish pheasant tails before the hatch because they work pretty good at imitating the sulphur nymphs in the stream and a pretty good amount of the fish will be key on the nymphs and emergers.

I dont have a real good emerger pattern, so maybe someone else could help you out with that.

Here's a nymph pattern that is deadly during a Sulpher hatch. I think it came from Rick Meyers, who developed it on Young Womans Creek. Tail: wood duck flank (brown Z-lon works as well) abdomen: dark brown dubbing, or pheasant tail. (fine copper wire if you use PT) Wing case: tie in some yellow dubbing with black ostrich on each side. This represents the adult ready to burst from the shuck. I tie it on a nymph hook (go one size higher than the adult) with a small amount of lead in the thorax. Fish this on a short dropper under you favorite pattern. In my experience, it will almost always catch the lions share, usually 10-1 over the dry. An exception was that June night on Spring, when it was cool and drizzling, and the trout took wildly for a couple of hrs. The next evening the nymph went right back to the head of the class. Sorry this isn't a more concise pattern listing: picked this up at a TU meeting many years ago. Now I have to tie a few fresh ones up; one of these evenings I might actually get to fish a hatch!

To answer CM's question. I connect the nymph to the bend of the hook of my dun pattern (usually a parachute, use your fav. dry but make sure it is bouyant) with 12-24'' of tippet one size lighter than my dry; 18'' being about average. No additional weight, the fly has a little lead in the thorax. Usually I end up with 5 and 6X flouro. Just fish it like you're dry fly fishing and when the dry slides under..... you know what to do, I'm sure! Sometimes swinging it it a bit at the end works, but most times just a good drift past rising fish will give the dropper plenty of motion. Those mid-drift mends will add some movenment as well. I'm sure you could fish this fly with any nymphing method you choose, but the above method is effective and fun, so I look foward to using it when the Sulphers are on.
